Soft rear brake after recall

[bcar00]

So I got a call back from the dealer who did my recall. I was surprised to hear that they got an answer from Triumph. The rep told them that certain bikes will get air accumulating in the ABS Module after "some period of non use." A week, two weeks? No idea, but the air is in the module and the only way to completely fix the spongy brakes is the Bleed ABS mode in the dealer service tool. No way to do it without the service tool (which I owned and sold as I didn't think I'd have further use for it, dohh!). He offered to run the procedure for me, but he's a 2-3 hour ride through horrendous Socal traffic.

Yep, bleeding without manipulating the abs module leaves the trapped air.
Even with the Triumph diagnostics tool getting it out is a pain in the rear caliper.

Funny how it worked fine for a few months, then went to soft again. I just got a pump to reverse bleed them so will see if it helps. I hate to even think about letting Triumph service ever touch it again.

I have exactly the same issue. Seemed good after the recall service but now really soft again!

Must be air in the line. Feels just like it!

Almost certainly.
